Introduction
This is a meter with RS232 and wireless GSM communication using Cicada GSMmodule. It has various event alerting functions including kWh remote reading and logging, using remote management and tampering provides customers a convenient remote reading method, on the air top-up. This meter is favored by customers and manufacturers with the features of high accuracy, wide measuring range andcompetitive cost performance.
Tariff
Tariff is software adjustable by energy provider as desired for meter.
Communication
Meter support RS232/2G/3G GSM, baud-rate: 115000.
Measurement
Meter measures voltage, current, active power and voltage is displayed on the 16x2LCD, accumulative power and top-up history is logged every 24 hours ontheweb-based software.
Mode
Meter has 2 operation modes:
- On the air top-up.
- STS token mode using keypad.
Over the air top-up
Over the air top-up is done via the web-based software available, with meter to be topped up pre-registered with a unique meter-id, the rest is handled between the software and firmware to top-up the corresponding meter whose meter-id is entered automatically.
STS operation
Enter 20-digit token via keypad available on meter, the token is generated from the website in event of network failure or malfunction.
